Description

[Detailed description of the invention] This invention relates to an improvement of a long gate used for wide frontages.

Conventionally, long telescoping gates with pantograph mechanisms and long folding doors have been known as gates of this type, but the opening/closing ratio (the length of the gate in the open and closed states) is even more important than these. This idea was devised for the purpose of increasing the ratio of

The present invention will be explained below based on the embodiments shown in the drawings.

FIGS. 1 to 4 are views showing a first embodiment of the gate of the present invention, and FIGS. 5 to 10 are views showing a second embodiment.

Both have parallel rails 1 laid on the ground,
Three support frames 2 are placed perpendicular to the parallel rail 1, and the lower part of the support frame 2 at one end is buried underground. As the support frame 2, a rectangular frame is used as shown in FIGS. 3 and 8, but this shape is not limited to this embodiment; other shapes include an L-shape and a triangle. There are many other possibilities. That is,
It is sufficient that the gate has a certain width in front and back and can generate a moment of restoring the gate itself.

The lower end of the support frame 2 is equipped with wheels 3 that are rotatably engaged with the parallel rails 1. In this embodiment, two sets of wheels 3 are installed at the front and rear of the lower end of the support frame 2. Each of the wheels is equipped with a wheel cover 4 to hold the wheel.

Adjacent support frames 2 are connected by a folding door 5, but in the first embodiment, adjacent ends of two telescopic fence bodies 6a having a vertical pantograph mechanism are connected by hinges 7 at two upper and lower locations. A folding door 5 which is bendable is used as the folding door 5, and in the second embodiment, a telescopic door 5 having a horizontal pantograph mechanism is used.
The vertical lattice 8 comrades at the adjacent ends of the fence bodies 6b,
The folding door 5 is used as a folding door 5 which is connected in a flexible manner by two upper and lower connecting plates 9 having cylindrical parts on the left and right sides into which the vertical lattice 8 is fitted.

Incidentally, the connection between the folding door 5 and the support frame body 2 may be any type having a hinge mechanism, and in the first embodiment, a normal hinge is used, and in the second embodiment, a connecting plate is used.

That is, the gate of this embodiment has a folding door 5 as one unit, which is made by connecting two telescopic fence bodies 6 in a flexible manner with a hinge 7 or a connecting plate 9, and the folding door 5 is connected via a support frame 2. It has a configuration in which the left and right sides are connected sequentially. Therefore, when closing the gate, the pantograph mechanism first contracts it so that it becomes as shown in Fig. 4 or 9, and then bends the gate in this state to make it as shown in Fig. 5 or 10. , it can be stored compactly between the supporting frames 2 that are closer to each other.

Since the gate of this invention has the above structure,
A gate with a much larger opening/closing ratio than conventional gates can be obtained, and the support frame improves self-supporting stability.

Furthermore, since the folding doors between the support frames can be manufactured as a unit and can be connected in sequence according to the purpose, it is an advantageous idea, as it is easy to manufacture and can be mass-produced.
